Abstract

The magnetostriction, dynamic strain coefficient and magnetization process of a 〈1 1 1〉 oriented twin-free Tb0.27Dy0.73Fe2 single crystal along the 〈1 1 1〉, 〈1 1 2〉 and 〈1 1 0〉 directions were investigated by strain gauge, lock-in amplifier, double coiled induction and Bitter Colloid techniques. It is found that a ‘jump' effect of magnetostriction along [1 1 ] and [2 1] directions occurs at a particular field and no ‘jump' effect occurs in the direction of [0 1 1]. The value of the magnetostriction along [1 1 ] direction is higher than that along [2 1] direction and the ‘jump' field for [1 1 ] direction is much lower than that for [2 1] direction. The magnetization process and dynamic strain coefficient, d33, of the Tb0.27Dy0.73Fe2 single crystal along the 〈1 1 1〉, 〈1 1 2〉 and 〈1 1 0〉 directions were also discussed. The 〈1 1 1〉 oriented twin-free Tb0.27Dy0.73Fe2 single crystal possesses excellent magnetostrictive properties along the rod direction (〈1 1 1〉) in low magnetic fields and it is very useful in applications of industry
